Subjective listening tests map manipulated acoustic variables to measured responses.

Evidence

The attributes of sound events are frequently called independent variables in experiment design and statistical analysis. In subjective tests, the independent variables are manipulated to produce different stimuli for testing, and when the selected test method is applied to the subjects, their responses (possibly after some post-processing) then yield the ‘dependent’ variable(s). The results should then reveal the relation of the ‘independent’ variable(s) to the ‘dependent’ variable(s), or in general the psychophysical function hi = f(s), as discussed in Section 8.1. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 949
